My time of the month differs from month to month. Generally I have three types of periods:
1. The good one
This one isn't too bad. Just blood and some small cramps. It generally comes the month after I have had a really bad period. I can have some salt or sugar cravings.
2. Let me sleeeep
For one to two periods after a good period I have the middle ground where I'm really tired, have some random cramping and milder back pains and stomach ache, I can get headaches really easily as well, but nothing extremely major. I can make it through a day with pain killers. Chocolate is a must during these periods.
3. FUCK EVERYTHING, I'M RIPPING OUT MY OVARIES!
Once every third to forth period I get these suuuuper bad cramps, stomach ache that goes all the way to the back like a knife and sometimes make me unable to move, I go between not being able to poop and then suddenly it turns into diarrhea. (Last one depends a bit, sometimes it's just diarrhea, sometimes it's just constipation and other times it goes between the two.) It's hell on earth D: Usually I can contain parts of the pain with pain killers, but it never helps completely. For the most parts I have no desire to eat during these times, and if I try to eat I tend to just feel sick because of it, so I don't eat that much.
Mentally though, I have never gotten mood swings or anything. If I'm really tired I might complain about my periods, but that's all that happens xD
